Webi have come up with a bruteforce solution. I will consider all pairs of a, b that have sum equal to n. And calculate the value of L C M ( a, b) = ( a ∗ b) / G C D ( a, b). ( G C D is greatest common divisor). But, this solution seems too slow when n <= 10 9. Is there a better solution for this problem ? +3 TuHoangAnh 14 months ago 4 WebTherefore, we applied the σ transform again.
